Workflow of the present invention: the automobile of advancing when motion is during through pressing plate, the gravity that vehicle weight produces is depressed pressing plate, drive piston and move downward compression fluid medium, fluid media (medium) in the cylinder body all is squeezed out cylinder body, fluid media (medium) collects the gravity energy that vehicle weight produces thus, the fluid media (medium) of band energy enters in the output channel by the delivery outlet of gravity collector and through No. 1 one way stop peturn valve, and the effect of No. 1 one way stop peturn valve is that fluid media (medium) refluxes when preventing that piston from moving upward.The fluid media (medium) of band energy is by output channel transmission and push No. 3 one way stop peturn valves open and enter into No. 1 accumulator and carry out energy storage.No. 1 energy storage pressure begins to rise, automobile high-speed is absorbed by accumulator 1 through the instantaneous pressure impact energy that gravity collector pressing plate is produced, the fluid pressure fluctuation that moment causes is in time eliminated, thereby the fluid media (medium) of band temporary impact energy is by No. 1 stable storage of accumulator.Along with the increased frequency of the automobile of advancing at a high speed through the gravity collector, numerous gravity collector pressing plates are depressed, the fluid media (medium) of band energy is also more and more, and the storing energy pressure in No. 1 accumulator is increasing, and institute's setting pressure table can show that No. 1 energy storage pressure stores situation.When fluid medium pressure reached decompression venting valve and sets force value, decompression venting valve was opened, and under the effect of adjustable choke valve, promoted hydraulic generator and carried out power generation operation thereby No. 1 accumulator begins slowly to discharge institute's storing energy.Adjustable choke valve fluid medium flow is controlled automatically, guarantees that hydraulic generator obtains required specified fluid media (medium) flow.When No. 1 accumulator energy storage arrived certain safety value, No. 1 safe pressure regulating valve was opened automatically and is unloaded stream, unloaded the stream fluid media (medium) and flow to storage tank by pipeline, thereby play the system protection effect.Because No. 1 accumulator slow lasting required steady pressure flow of release hydraulic generator under the effect of voltage-stabilizing system, hydraulic generator must send the electric current of burning voltage, thereby plays pressure stabilization function.The pressure regulation value of No. 1 safe pressure regulating valve is set according to the storage size of No. 1 accumulator.The cushioning effect of accumulator, and the acting in conjunction of decompression venting valve and adjustable choke valve under, the fluid media (medium) output pressure stable flow pusher hydrodynamic pressure generator of band energy generates electricity.
After automobile leaves gravity collector pressing plate, effect lower cylinder body inner carrier at spring is pushed back the origin-location, at this moment produce vacuum in the cylinder body and cause negative pressure, under the effect of the negative pressure that vacuum causes, the fluid media (medium) in the fuel tank is pushed No. 5 one way stop peturn valves open through input channel and open No. 2 one way stop peturn valves and prepare through overcompression for automobile next time through cylinder body input hole inlet flow body medium.But because if automobile quantity is too much, can cause the cylinder body inner carrier to have little time to promote gravity collector pressing plate gets back to the origin-location and just may be depressed for the second time and cause piston to flog a dead horse downwards, influence the stable supply of flow system flow, thereby cause the under-supply generating efficiency that influences of system fluid rate-of flow.Respond fast for reaching oil suction, the purpose of gravity collector pressing plate returning quickly regime flow, shorten the gravity collector response time, improve system works efficient, by the low pressure and mass flow hydraulic pump gravity collector cylinder body is carried out repairing.For this reason, the low pressure and mass flow hydraulic pump will keep certain little pressure in whole oil suction loop and gravity collector cylinder body, thereby make the gravity collector guarantee input and output fluid media (medium) amount stable and that respond fast.The under-supply low-response that causes of flow in whole oil suction input channel and gravity collector cylinder body, input channel internal pressure are lower than when setting limiting value, and pressure switch detects the low signal enabling low pressure and mass flow hydraulic pump that sends of input channel pressure automatically.After hydraulic pump starts, fluid media (medium) is pushed No. 4 one way stop peturn valves open and is entered into input channel, and open No. 2 one way stop peturn valves and enter cylinder body and keep certain input pressure by the cylinder body input hole through input channel, improve the input speed of inlet flow body medium, oil suction responds fast, the purpose of gravity collector pressing plate returning quickly regime flow thereby reach; Meanwhile, also to No. 2 accumulator accommodating fluid media, No. 2 accumulator begins storing energy to hydraulic pump, when the storage pressure of No. 2 accumulators reaches the required force value of gravity collector, pressure switch will detect pressure signal automatically and close hydraulic pump, at this moment, and the hydraulic pump fuel cut-off.No. 2 accumulator plays gravity collector pressurize effect simultaneously, guarantees the supplying fluid medium of gravity collector, thereby reaches the purpose of regime flow.When whole oil suction circuit pressure was higher than limiting value, No. 2 safe pressure regulating valves were opened automatically and are unloaded stream assurance system safety, and institute's fluid media (medium) that unloads is through the channel flow oil sump tank.Use external power source when the low pressure and mass flow pump starts first in system, can use self-powered after the normal operation.
Beneficial effect of the present invention: the present invention generates electricity, and to enter storage battery standby, and enter the charging of vehicle charging website steam supply car, also can go into electrical network, automatic voltage regulation is exported, can be carried out integrated combination according to required energy output, energy output is adjustable, does not consume any energy such as gasoline, diesel oil, coal, natural gas, and pollution-free, nothing is discharged, noiseless, equipment is small and exquisite, the integrated level height is invested little convenient for installation and maintenancely, can reach unattended duty, cost of electricity-generating is extremely low, and development prospect is very wide.
